Learn GO Fast: Golang for Experienced Devs

Learn about constants, variables, and basic data types in Go, including int, int8/16/32/64, unsigned ints, float32/64, string and boolean, default values, type inference, and constants.

Learn Go functions, parameters, and returns, including multiple values and error handling, then compare if/else, switch, and conditional switch for robust control flow.

Explore arrays, slices, maps, and loops in Go, covering memory layout, indexing, capacity, and the append and delete operations.

Explore how strings relate to runes and bytes in Go, examine UTF-8 encoding, and learn to index, iterate, and build strings efficiently.

Define structs with named fields and attach methods to compute miles left. Use an interface with a miles left method to generalize gas and electric engines.

Learn how pointers in Go store memory addresses, use the star syntax to dereference, handle nil pointers, and employ ampersand and new to allocate memory efficiently.

Learn to use go routines to run tasks concurrently and achieve parallel execution on multi-core CPUs, while using wait groups and mutexes or a read-write mutex to safely share data.

Explore channels and goroutines in Go, including unbuffered and buffered channels, blocking behavior, deadlocks, range iteration, closing channels, and select statements for concurrent patterns.

Learn how go generics enable a single sum slices function for int, float32, and float64 via type parameters and inference, with json unmarshalling and generic structs.
